Relationship between palaeohydrochemical traces and in-situ leachable sandstone type uranium mineralization;

Because the geomechanical environment in the northeastern area of Sichuan basin is complicated and unstable,the combination of structural features is special,especially the planar structural feature.

Basing on the formation and characteristic of the oil storage structure in Lamadian, this paper discusses the evolution and formation process of various types of geologic structural feature in the geohistorical background of Daqing Placanticline structure and special mechanic support.

By using electro hydraulic servo technical, the jaws realize the action of turning, pitching and stretching, the workbench can prop up in any angle, the forming trajectory can be achieved in this system.
